Drilling Essential
High-Speed Steel M35
HSS-E M35 is a type of high-speed steel that contains a certain amount of cobalt. Cobalt is added to high-speed steel to increase its hardness, heat resistance, and durability. The HSS-E M35 material has superior properties such as high toughness, wear resistance, and hot hardness, making it ideal for drilling hard materials such as stainless steel, alloy steel, and titanium. HSS-E M35 drill bits can also maintain their sharpness and cutting ability at high temperatures and under high loads, making them suitable for use in high-speed drilling operations.
Two flute spiral design
Two flute spiral design also lets the material particles escape easily for a much more clean drilling operation. The service life of the drill bit is greatly increased.
